ABSTRACT

The quantitative zone-axis CBED pattern matching technique developed by Bird and Saunders is applied to low-order structure factor refinements from the metals nickel and copper. A new method is proposed for determining which structure factors can be refined from a specific data-set. The validity of the widely used correction potential for thermal diffuse scattering (TDS) is considered by comparing CBED refinement values of the imaginary structure factors to those given by the Einstein model. In addition, the importance of second-order TDS corrections in bonding studies is investigated.
